What this topic is asking
Topic 3.9 covers the right to privacy, a right the Constitution never names explicitly. The College Board wants you to explain how the Court derived privacy from the due process clause and why this is controversial. The required case is Roe v. Wade.
A right not in the text
Unlike speech or counsel, privacy is not enumerated. The Court built it from the idea that the due process clause protects "liberty", and that liberty includes a sphere of private personal decisions.
This kind of reasoning, finding fundamental liberties within "due process", is called substantive due process: the idea that the clause protects not just fair procedures but certain substantive freedoms.
Roe v. Wade (1973)
Why the right is controversial
Because privacy is not written into the Constitution, the topic is genuinely contested:
- Critics argue that recognizing unenumerated rights lets unelected judges impose their own values, undermining democratic accountability and judicial restraint.
- Supporters argue that the Ninth Amendment and the due process clause show liberty was never meant to be limited to a literal list, and that some private decisions deserve protection.
The exam wants you to be able to argue both sides, then defend a thesis.
How this topic connects across the course
The right to privacy is the unit's clearest example of constitutional interpretation as a live, contested process, which ties it directly to Unit 2. Topic 2.10 (The Court in Action) and Topic 2.9 (Legitimacy of the Judicial Branch) ask how the Court's choices about interpretation affect policy and its own standing. The privacy line of cases is the case study: when the Court reads "liberty" expansively, supporters praise it for protecting freedom and critics accuse it of judicial activism (Topic 2.10) that threatens its legitimacy (Topic 2.9). You can use the privacy debate as concrete evidence whenever an Argument Essay asks about judicial activism or interpretation.
The topic also links forward to Unit 4. Whether the Court should recognize unenumerated rights is, at bottom, a question about the role of government and the balance between liberty and order, which is exactly the terrain of social policy in Topic 4.10. A socially liberal position tends to favor protecting private decisions from government, while a socially conservative position tends to favor traditional regulation. Connecting the privacy debate to ideology shows the examiner you can move between the constitutional and the political, which is the synthesis the course is built to test.
Try this
Q1. Explain how the Court located a right to privacy despite no explicit text. [Short explanation]
- Cue. It read "liberty" in the Fourteenth Amendment's due process clause to include certain private decisions, an approach called substantive due process.
Q2. Identify why the right to privacy is controversial. [Recall]
- Cue. It is not enumerated, so critics argue judges are creating rights, while supporters argue liberty extends beyond the literal text.

A SCOTUS Comparison FRQ, 4 points.
A. Identify: the due process clause of the Fourteenth Amendment, from which the Court derived an implied right to privacy.
B. Explain the similarity: both involve a state law regulating a private personal decision challenged as violating the right to privacy.
C. Apply the reasoning: in Roe the Court held the right to privacy protected certain personal medical decisions from state interference within limits, and the same due-process privacy reasoning could be applied to the scenario.
Markers reward identifying the implied right grounded in the due process clause.

An Argument Essay FRQ, 6-point rubric.
Thesis (1): e.g. "The Court should recognize unenumerated rights cautiously, because liberty under the due process clause extends beyond the literal text."
Evidence (up to 3): the Ninth Amendment's reference to unenumerated rights; the Fourteenth Amendment's due process clause; Federalist No. 78 on judicial interpretation.
Reasoning (1): explain how the due process clause supports protecting fundamental liberties not listed by name.
Alternative perspective (1): concede that recognizing unstated rights risks judges imposing values, then argue restraint plus textual grounding limits the danger.
